Heat 1 tablespoon of extra virgin olive oil in a large nonstick skillet over medium high heat. Add the sausage and cook, using a spatula to break it up into small pieces. Continue cooking until the sausage is well browned, about 15 minutes.
Add the minced garlic to the sausage and let cook for 1 minute or so, until fragrant. Then remove the sausage and garlic to a plate and set it aside for later.
Return the skillet to the stove top. Add 1 tablespoon of olive oil and all of the beef broth to the skillet. Bring to a boil and let cook for 1 minute to reduce slightly. Add the chard and cook, uncovered, for about 7 minutes, or until the chard is tender.
Meanwhile, bring a large pot of salted water to a boil. Add the fusilli and cook according to package directions, about 10 minutes. When the pasta is tender, reserve 1/2 cup of the cooking water and drain the pasta.
Add the drained fusilli to the skillet that has the Swiss chard. Add the sausage back to the skillet as well and toss to combine. Add a bit of the reserved pasta water if the pasta seems dry. Sprinkle the pasta with the feta cheese and fresh herbs. Season generously with kosher salt and freshly cracked black pepper, and drizzle with another two tablespoons of olive oil. Toss to combine, then serve.
